I hear that the glow plugs can stay energized for up to 2 minutes, but is there a way to tell in the cab if they're on or not?
I've waited 30 seconds (wait to start light was out in 5 seconds or so) and that's not seemed to help. I occasionally will get one puff and then nothing for a couple more tries.
Do I need to wait longer or do anything different?
Yes, they can stay on for up to 2 minutes but there is nothing in the cab that lets you know there still on. Sounds like your GPR (glow plug relay) is bad, I would suggest the stancor 586-902 12v GPR. It's a nice relay and is quite a bit bigger, I have one on mine and I haven't burned up a relay since. Do a search on the Stancor mod. You can get them for $50 from Mouser Electronics. Read the winter operation by NCHornet it's a sticky at the top of page above the threads.
